On Saturday afternoon, thousands gathered at Colorado’s Capitol for a peaceful protest during which protesters laid face down on the ground with their hands behind their backs chanting “I can’t breathe,” some of George Floyd’s last words before he died. The demonstration lasted for 9 minutes, roughly the length of time Minneapolis cop Derek Chauvin pressed his knee into the back of Floyd’s neck.

The video, originally posted on the Colorado Times Recorder’s Twitter page, has received over 6.5 million views.
